Silica Chloride Nano Particle Catalyzed Synthesis of 2,2′-(arylmethylene)bis(5,5-dimethylcyclohexane-1,3-dione) Derivatives

Silica chloride nano particle (nano SiO(2)-Cl), has been found to be heterogeneous catalyst for facile and simple condensation of dimedone with aromatic aldehydes into 2,2'-(arylmethylene)bis(5,5-dimethylcyclohexane-1,3-dione) derivatives in dry CH(2)Cl(2). (doi: 10.5562/cca1721)
